Marine Weather and Tides
Jackson, MS

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

00z TAF discussion:
expecting isolated to scattered thunderstorms through the evening
hours to potentially affect ground operations and bring brief
MVFR ifr conditions to pib hbg jan hks gwo glh. Erratic and gusty
winds are also possible with any storms impacting on station. At
jan hks, anticipate consolidated thunderstorm outflow to switch
surface winds to out of the southeast by 01 utc and lasting
through approximately 03 utc. Most of the convection should
diminish late tonight although some lingering areas of isolated
storms cannot be ruled out. Late tonight MVFR flight cat
reductions (with potential for isolated and brief ifr
restrictions) will be possible around the region, particularly in
areas such as hbg pib (that received downpours today). Tomorrow,
winds will tend to be very light in variable, except around
scattered to numerous midday to afternoon showers and
thunderstorms. Bb

Discussion
Friday night through Wednesday night A very wet long term forecast
is in store for the arklamiss. Convection will be ongoing across
the area Friday evening as abundant moisture combines with decent
lapse rates and upper level troughing across the area. Most of the
convection will dissipate during the evening hours, but some
showers storms could persist into the overnight. Little will
change on Saturday as 1.7-1.9 pwats continue over the area, and
this combines with decent mid level lapse rates. Expect diurnal
convection to form over much of the area once again, diminishing
during the evening hours. With all of the moisture and cloud
cover, expect high temperatures to top out in the mid upper 80s
Saturday.

As we progress through the weekend all eyes shift to the gulf as a
potential tropical system develops. There is still uncertainty as
for the development of this system, but NHC currently has a 90%
chance of formation over the next 5 days. The potential
development and movement of the system will dictate our weather
for Sunday through Tuesday. Both the gfs ECMWF are in decent
agreement that any potential system would begin to affect the area
on Monday. For now, will begin to mention the potential for heavy
rains flooding in graphicast and hwo beginning on Monday, as wpc
has increased rainfall amounts for these areas. 15
rest of today through tomorrow...

convection has been slow to develop this afternoon due to lingering
debris clouds from last night's storms that were slow to dissipate.

Nonetheless, convection is starting to increase across southern and
eastern portions of the area with a few showers and storms over
areas of the delta where gaps in the morning cloud cover were
present. Overall thinking hasn't changed much with convection
expected to continue to increase in coverage across at least the
south and east portions of the area with composite outflow boundary
interactions helping to generate new activity further northwest
towards the natchez trace corridor, however the northwest extent
remains uncertain as the environment has been slower to recover from
the morning clouds. Latest mesoanalysis still indicates the
potential for a few of these storms to become strong to possibly
severe with the main threat confined to wet microbursts and small
hail. In addition, pwats near 1.75" will support the threat for
locally heavy rainfall and isolated flash flooding due to weak flow
aloft. As we head into tonight, activity will begin to wane with the
loss of daytime heating, however a few showers and storms could
linger during the overnight hours. A weak shortwave trough will
encroach on the region overnight from the northwest and will provide
enough support to help keep these lingering showers around overnight.

For tomorrow, the presence of the aforementioned trough and
plentiful moisture will combine with daytime heating for another
round of showers and thunderstorms. Latest guidance is in good
agreement that showers and storms should get an earlier start with
showers possible as early as the early to mid morning hours with
coverage increasing through the late morning into the afternoon. As
has been the case this week, 3000-4000 j kg of SBCAPE and 6-6.5 c km
mid-level lapse rates will support a continued diurnal threat for a
few isolated wet microbursts and small hail in addition to locally
heavy rain. Due to the limited coverage will not mention the severe
or flash flooding threat in the hwo graphics. Greater cloud coverage
will keep high temperatures cooler with mid to upper 80s across the
area. Tw

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
